Answer:
452.4 cm
Step-by-step explanation:
the formula for the area of a circle is A = pi r^2
Answer:
t =17 years
Step-by-step explanation:
The formula for interest
A = P(1+ r/n)^ nt
where a is the amount in the account , p is the principal, r is the rate, n is the number of times compounded per year and t is the time in years
Substituting in what we know
690 = 460 ( 1+ .024/365)^ 365t
690/460 = ( 1+ .024/365)^ 365t
1.5 = ( 1+ .024/365)^ 365t
Taking the log of each side
log(1.5) = 365t log( 1+ .024/365))
Dividing each side by( 1+ .024/365)
log(1.5)/ log( 1+ .024/365) = 365t
divide each side by 365
1/365 log(1.5)/ log( 1+ .024/365) =t
t =16.8949
To the nearest year
t =17
Answer:
- <u>The odds are 2 : 23, or about 0.09 : 1 (0.09 to 1).</u>
Explanation:
The <em>odds </em>of an event is the ratio of occurrence to non-occurrence of the event.
When you know the <em>probability</em> of an event, then you can calculate the odds by dividing the probability of occurence by the probability of non-occurrence.
Calling p the probability that an event will happen, 1 - p is the probability that it will not happen and the odds will be:
You have p = 8% = 0.08, and 1 - p = 1 -0.08 = 0.92.
Therefore:
- Odds = 0.08 / 0.92 = 8 : 92 = 2 : 23 ≈ 0.09 : 1 (0.09 to 1)
Let’s divide 48 by 16 to see how many cents per inch of wire. 48/16=3 so it costs 3 cents per inch of wire. now all we have to do is multiply 47 by 3, and you will get 141 cents, or $1.41.
